ADDENDUM: Included with user manuals for machines with a CAT5 connector
This addendum describes the Power Connect feature used with Kramer
machines, and the choice between STP and UTP CAT5 cables.
Power Connect Feature
1
The Power Connect feature lets you power a transmitter / receiver system by
connecting just one power adapter to either the transmitter or the receiver. The
other unit is fed over the same CAT5 cable.
The Power Connect feature applies as long as the CAT5 cable is heavy gauge
cable (that is, it can carry power). The distance does not exceed 50 meters on
standard cable.
For a distance of 100 meters, separate power supplies must be connected to the
transmitter and to the receiver simultaneously, unless using heavy gauge CAT5
cable.
Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
The decision whether to use shielded twisted pair (STP) cable or unshielded
twisted pair (UTP) cable depends on the nature of the application.
It is recommended that in applications with high interference, shielded twisted
pair (STP) cable will give better results. However, the shield itself does create a
capacitance that degrades the frequency response of the machines. For shorter
distances, of 50m or so, shielded twisted pair (STP) cable is preferred because it
provides protection from interference (degradation is non-apparent).
For a long range application, unshielded twisted pair (UTP) cable is preferred.
However, the unshielded twisted pair (UTP) cable should be installed far away
from electric cables, motors etc., which are prone to create electrical interference.
1 This section of the addendum is only relevant to machines that support this feature (for example, the TP-104; not the
TP-100)

3 Overview
The Kramer VP-6A is a high performance distribution amplifier for computer
graphics (UXGA) video and audio signals. The VP-6A accepts:
 One computer graphics input: provides correct buffering and isolation,
and distributes the signal to six outputs on 15-pin HD connectors, and one
twisted pair output

 A stereo audio input signal: either
1
an unbalanced stereo audio input
signal on a 3.5mm mini jack, or a balanced stereo audio input signal on a 5-pin
terminal block connector. The VP-6A outputs 12 stereo audio signals
simultaneously: six unbalanced stereo audio signals on 3.5mm mini jacks, and
six balanced stereo audio signals on 5-pin terminal block connectors. If the
selected audio input is unbalanced, it is converted to balanced stereo audio; if
the selected audio input is balanced, it is converted to unbalanced stereo audio
The VP-6A can:
 Power the receiver over the same CAT5 cable
 Be used with the TP-122 XGA / Audio Line Receiver (converting the
CAT5 signal to XGA, stereo analog and S/PDIF digital audio outputs) or with
the TP-120 XGA Line Receiver (converting the CAT5 signal to an XGA output)
In addition, the VP-6A features:
 Switches on the underside for ID Bit control and sync polarity
 Front panel controls for UXGA equalization, as well as left and right
audio level controls
 A video bandwidth of 500MHz that ensures transparent operation at all
graphics resolutions
 A transmission range of more than 300 ft. (more than 100 meters) over
UTP cabling
To achieve the best performance:
 Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise levels
(often associated with low quality cables)
 Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VP-6A away
from moisture, excessive sunlight and dust
In applications with high interference, shielded twisted pair (STP) cable will
give better results.

The example in Figure 3 illustrates how to output a computer graphics signal
(and audio) from a computer to up to six local monitors, as well as how to
transmit it over UTP cabling to a TP-122 XGA / Audio Line Receiver.
To connect the VP-6A and a TP-122, do the following:
1. Connect a computer graphics source (for example, a computer) to the
INPUT HD15F connector and to the UNBAL. AUDIO IN 3.5mm mini
jack, for example, using a Kramer C-GMA/GMA cable
1
. Press in the IN
SELECT button.
Alternatively, connect a computer graphics source to the INPUT HD15F
connector, and a balanced stereo audio source to the BAL. AUDIO
INPUT 5-pin terminal block connector, and release the IN SELECT button.
2. Connect the OUTPUT HD15F connectors to up to
2
six acceptors (for
example, Local Display 1 to Local Display 6).
3. Connect up to
2
12 stereo audio outputs
3
, that is, up to six:
 Unbalanced stereo audio OUT 3.5mm mini jacks, and
 Balanced
4
stereo audio 5-pin terminal block connectors (see section 5.1)
4. Connect
5
the CAT5 RJ-45 LINE OUT connector
6
to the LINE IN RJ-45
connector on a Kramer CAT5 receiver, such as the TP-122 unit.
5. Connect the power cord
7
to the VP-6A (not illustrated in Figure 3).
6. On the VP-6A:
 Adjust
8
the UXGA cable compensation equalization level and/or the
audio level, if required
 Set the ID BIT switches 4 and 11 on the underside to ON (by sliding
them to the left). This would enable a notebook or laptop (if connected instead
of a computer) to output an UXGA signal to an external VGA monitor
1 XGA HD15M +Audio jack to XGA HD15M +Audio jack (not supplied). The complete list of Kramer cables is on our Web
site at http://www.kramerelectronics.com. Alternatively, you can connect an XGA source to the XGA INPUT HD15F
connector, and a separate audio source to the UNBAL. AUDIO IN
2 When not all outputs are required, connect only the outputs that are required and leave the other outputs unconnected
3 Note, that if the selected audio input is unbalanced, it is converted to balanced stereo audio; if the selected audio input is
balanced, it is converted to unbalanced stereo audio
4 By wiring the balanced outputs as unbalanced (see Figure 5) you can output 12 unbalanced stereo audio outputs
5 Via UTP cabling, with a range of more than 300ft (>100m): see section 5.1
6 The TP-122 (or TP-120) may be powered via this connector (instead of via the 12VDC external supply)
7 We recommend that you use only the power cord that is supplied with this machine
8 Use a screwdriver to carefully rotate the trimmer, adjusting the appropriate level

 If necessary, slide the VS and HS switches to the right to output negative
sync polarity (or leave them in the left position (Normal) to retain the sync polarity)
7. On the TP-122:
 Connect the XGA OUT HD15F connector to the XGA acceptor (for
example, a display), and connect the AUDIO OUT S/PDIF RCA connector to the
digital audio acceptor (for example, an AV Receiver), and the ANALOG 3.5mm
mini jack to the analog audio acceptor (for example, a stereo audio recorder)
